Abstract

The nuclear excited states of 50Cr were studied by means of the decay of 1.7 min 50Mn, the 50Cr(p, p' γ) and 52Cr(p, t) reactions and Coulomb excitation with 35Cl ions. Gamma-ray branching ratios and precise level energies were obtained for 23 excited states in 50Cr. The L-values from the (p, t) reaction are employed to suggest or confirm the spin and parity assignments for eight excited states. The mean lifetime of the 783.3 keV 2+ state was determined as 12.1 ± 1.2ps from the measured B(E2)↑ value and as 10 ± 2ps from Doppler-shift measurements. The experimental level scheme for 50Cr is compared with that for the cross-conjugate nucleus 46Ti and with a calculated level scheme.
